tor/user must be observed at all times.
General Safety Directions for the Operator/User
– If hot or cold machine parts pose a danger, such parts
must be protected by the operator/user against contact
with personnel. Protective covers for moving parts (e.g.
coupling) must not be removed when the machine is
running. Leakages (e.g. at the shaft seal) of hazardous
pumping media (e.g. explosive, toxic, hot liquids) must
be disposed of in such a way that any danger for per-
sonnel and the environment is removed. All government
regulations must be observed at all times. Any danger
to persons etc. by electrical energy must be excluded.
(For details see e.g. regulations of VDE and the local
utilities).
